Hadith 1:530

Narrated Abu Huraira:

Allah's Apostle said, "Angels come to you in succession by night and
day and all of them get together at the time of the Fajr and 'Asr
prayers. Those who have passed the night with you (or stayed with you)
ascend (to the Heaven) and Allah asks them, though He knows everything
about you, well, "In what state did you leave my slaves?" The angels
reply: "When we left them they were praying and when we reached them,
they were praying."
